The management of baldness is a multidisciplinary effort that spans the medical, pharmaceutical, food supplement, exercise and fashion industries. Androgenic alopecia, alopecia areata, and telogen effluvium are the primary nonscarring alopecias.[1] The most common cause of hair loss in men is androgenic alopecia, the early stages of which can be slowed or reversed with medication, while more advanced cases may be amenable to hair transplantation. Alopecia areata presents as focal discoid patches of hair loss, and affects up to 2% of the U.S. population, occurring more often in children. Telogen effluvium can occur after stressful events, including severe illness, childbirth, or high fever, and can be seen with certain medications or deficiency of iron, particularly in females.[1] Thyroid dysfunction, both when increased and decreased, can lead to specific patterns of hair loss.Exercise can impact androgenic hair loss at least partially by affecting androgen and estrogen levels.
Quantification of androgen indices in response to exercise can be understood in four categories: short versus long term, and anaerobic versus aerobic. These are indirect assays of exercise impact on hair loss, although the ability of exogenous androgen to worsen or precipitate miniaturization in the genetically predisposed is well documented.[12] Investigations have been either self-report, or cross-sectional and cohort studies with exercise and serum hormonal indices, but no phase III clinical trials. In some studies, conflicting results are thought related to differences in exercise mode, volume, or physical condition of subjects.[13]
In cross-sectional analyses, aerobic exercisers have lower basal total and free testosterone compared to the sedentary.[14][15][16][17] Anaerobic exercisers also have lower testosterone compared to the sedentary[14] but a slight increase in basal testosterone with resistance training over time.[18] Acutely, testosterone briefly increases when comparing aerobic, anaerobic and mixed forms of exercise.[19] A study assessed men who were resistance trained, endurance trained, or sedentary in which they either rested, ran or did a resistance session. Androgens increased in response to exercise, particularly resistance, while cortisol only increased with resistance. After initial post-exercise increase, there was decline in free and total testosterone during resistance recovery, particularly in resistance-trained subjects. Endurance-trained subjects showed less change in hormone levels in response to exercise than resistance-trained subjects.[20] Another study found relative short term effects of aerobic, anaerobic and combined anaerobic-aerobic exercise protocols on hormone levels to not be different. It showed increases in testosterone and cortisol immediately after exercise that returned to baseline in 2 hours.[21]
In trained long term aerobic exercisers, basal androgen levels are unchanged,[22] or decreased.[21][23] Acutely, endurance based aerobic efforts cause testosterone to rise.[24] A year long, moderate-intensity aerobic exercise program increased DHT and SHBG in sedentary men age 40-75, but had no effect on other androgens. Both DHT and SHBG increased 14% in exercisers at 3 months, and at 12 months they remained 9% above baseline. SHBG is protective against DHT as it binds free androgen.
